Problems with graphics

[michaeltheiii]

I mostly just play Super Mario 64, but I have noticed problems and I hope someone can answer my questions.

1. Unless I am on slopes, my shadow doesn't show.


2. Inside, the Sun Carpet never shows up unless I'm at the one spot in this picture, and it only shows half of it.



If I switch in the graphics settings from Direc3D HAL to RGB Emulation, these are fixed, but PJ64 runs extremely slow and Mario appears black in the beginning title page.


Can anyone help me with this?
